How to charge an electric vehicle: tips for preserving the battery
The use of electric vehicles in the workplace is growing rapidly due to the sustainability and cost-saving benefits. To ensure long battery life and maximize efficiency, it is essential to follow some good charging practices. In this article, we will guide you on how to properly charge your electric work vehicle, avoiding common mistakes and maximising battery life.
How to recharge to preserve the battery of an electric vehicle:
Use your electric vehicle as much as possible
Using your electric vehicle (EV) frequently not only allows you to take full advantage of its environmental and economic benefits but also helps preserve the health of the battery. Lithium-ion batteries, commonly used in EVs, work best when they are regularly charged and discharged. Constant use helps keep internal chemical flows active, preventing material degradation and buildup of deposits that can reduce battery capacity. Conversely, leaving the vehicle unused for long periods can cause deep discharge and accelerate wear and tear. By driving regularly and keeping the charge level between 20% and 80%, stress on the cells is reduced, prolonging battery life. In addition, frequent use allows you to better monitor performance and detect any abnormalities in time. In short, using your electric vehicle frequently is a simple habit that is good for both the environment and your vehicle.
Limit the use of fast charging and prefer regular charging
There are several methods for charging an electric vehicle, and choosing the right one is critical. Slow charging (AC): Perfect for overnight charging or long periods of inactivity. It helps preserve the battery, preventing thermal stress and premature degradation. This type of recharging is recommended for those who can leave the vehicle idle for several hours, such as overnight or on rest shifts. It is also the most economical method in terms of electricity cost. Fast charging (DC): Ideal for emergencies or fast charging needs. However, excessive use of fast charging can overheat the battery and reduce its useful life. This method is very useful for vehicles used intensively during the workday, but it is important not to abuse it to avoid stress on the battery. If possible, alternate fast charging with slow charging sessions to balance the effect on the system. Ultra-rapid charging: available at some public stations, can be useful in special cases, but is not recommended for frequent use. This type of charging can bring the battery to very high temperatures, accelerating the chemical degradation process. It is advisable to use it only in situations of extreme necessity, such as during long journeys or in operational contexts that require minimal charging time.
Plan recharges according to vehicle use
If your vehicle is used intensively during the day, plan recharges strategically to avoid having to use fast charging all the time, which can accelerate battery degradation. For example, if your vehicle is stationary during the lunch break or at other times of inactivity, you could take advantage of partial slow charging, keeping the battery between 40 percent and 80 percent. In addition, if you can schedule charging, take advantage of time slots when energy is cheaper and the electrical system is less stressed, thus reducing operating costs. A well-planned approach keeps the battery efficient for longer and optimizes the vehicle range during the workday.
Avoid leaving the vehicle stationary for an extended period with a fully discharged battery
If you are not using the vehicle for extended periods, avoid leaving it with a fully discharged (0%) battery. Ideally, keep the battery around 50-60%, a level that minimises chemical stress on the cells. If you know the vehicle will be unused for weeks or months, check the charge level periodically and, if necessary, recharge it slightly to keep it in the optimal range. Also, if possible, store the vehicle in a temperature-controlled environment to prevent further damage from extreme weather conditions. Avoid exposing the vehicle to high temperatures; in summer, for example, it is preferable to park it in the shade. Also, if the temperature is high, charging is slower.
